I actually like distinct rules.I think that it's beyond assinine that, for the last 37 years, the two leagues have played under different rules.
I personally don't care if there's a DH or not, just play by the same rules.
In fact, I preferred it when the two leagues were even more distinct by never playing against each other in the regular season, using different umpire crews, using different set of rules for meetings at the mound, and having two distinct league presidents.
Baseball, unlike other sports, is made of 2 different leagues.
